Hi, I am recieving this exception and I really have no idea where to look for the problem, or what may be causing this. If someone can point me in the right direction that would be great. Can someone give me a common reason why this exception would be thrown?

Thanks in advance,

James B

Do you call AbstractXMPPConnection.disconnect() for every connection before terminating your program?

No not at the time when I created this discussion. However I have added code to disconnect connection when I am finished. I have not yet had a chance to test this. Do you think this may have been the cause of my problem?
